Are there any ground covers that are invasive and should be avoided? Yes, certain ground covers, while beneficial for controlling erosion and adding greenery, can become invasive, outcompeting native plants. It’s crucial to identify these species to prevent potential ecological harm and maintain biodiversity in your garden.
What Are Invasive Ground Covers?
Invasive ground covers are plant species that spread aggressively, often outside their native habitats, and can disrupt local ecosystems. They tend to outcompete native plants for resources, leading to reduced biodiversity. Some common invasive ground covers include:
- English Ivy (Hedera helix): Known for its ability to climb and spread rapidly, this plant can smother trees and understory plants.
- Periwinkle (Vinca minor): Often used for its attractive flowers, periwinkle can form dense mats that inhibit the growth of native flora.
- Japanese Pachysandra (Pachysandra terminalis): While effective for shade gardens, it can overrun areas, making it difficult for other plants to thrive.
- Creeping Jenny (Lysimachia nummularia): Appreciated for its bright foliage, this plant can quickly take over garden spaces and natural areas.
Why Should You Avoid Planting Invasive Ground Covers?
Planting invasive ground covers can lead to several ecological and maintenance issues:
- Ecosystem Disruption: These plants can alter soil chemistry and hydrology, impacting native plant and animal species.
- Biodiversity Loss: By dominating landscapes, invasive ground covers reduce the variety of plant and animal life.
- Increased Maintenance: Managing invasive species requires significant effort to control their spread, often necessitating chemical or manual removal methods.
How to Identify Invasive Ground Covers?
Identifying invasive ground covers involves understanding their growth patterns and characteristics. Here are some tips:
- Rapid Growth: Invasive species often exhibit fast growth and spread, quickly covering large areas.
- Dense Mat Formation: They form thick mats that suppress other plant life.
- Climbing Ability: Many invasive ground covers can climb trees and structures, causing damage.
Alternatives to Invasive Ground Covers
To maintain a healthy garden ecosystem, consider these non-invasive alternatives:
- Wild Ginger (Asarum canadense): A native option that provides lush, green coverage without aggressive spreading.
- Foamflower (Tiarella cordifolia): Offers attractive foliage and flowers, suitable for shady areas.
- Barrenwort (Epimedium spp.): Known for its delicate flowers and resistance to deer and pests.
- Creeping Thyme (Thymus serpyllum): A low-growing herb that provides aromatic foliage and small flowers.

| Feature | English Ivy | Wild Ginger | Foamflower |
|---|---|---|---|
| Growth Rate | Fast | Moderate | Moderate |
| Invasiveness | High | Low | Low |
| Maintenance | High | Low | Low |
| Native to North America? | No | Yes | Yes |
How to Manage Invasive Ground Covers?
If you already have invasive ground covers in your garden, consider these management strategies:
- Regular Monitoring: Keep an eye on the growth and spread of these plants.
- Physical Removal: Hand-pull or dig up small infestations before they spread.
- Mulching: Use mulch to suppress growth and prevent seed germination.
- Herbicides: Apply targeted herbicides for larger infestations, following environmental guidelines.
People Also Ask
What is the most invasive ground cover?
English Ivy is considered one of the most invasive ground covers due to its rapid growth and ability to smother trees and structures. Its aggressive nature makes it difficult to control once established.
Can I plant ground covers in shaded areas?
Yes, many ground covers thrive in shaded areas. Foamflower and Wild Ginger are excellent choices for shaded gardens, offering attractive foliage and low maintenance.
How do I replace invasive ground covers?
Begin by removing the invasive plants, ensuring you get as much root material as possible. Prepare the soil and plant non-invasive alternatives like Creeping Thyme or Barrenwort. Regularly monitor the area to prevent regrowth.
Are there native ground covers that are non-invasive?
Yes, many native ground covers are non-invasive and beneficial for local ecosystems. Wild Ginger and Foamflower are native to North America and provide excellent coverage without the risk of becoming invasive.
What are the benefits of using native ground covers?
Native ground covers support local wildlife, require less maintenance, and are adapted to the local climate, making them more resilient and environmentally friendly.
Conclusion
Choosing the right ground covers is essential for maintaining a healthy and sustainable garden. By avoiding invasive species like English Ivy and opting for native alternatives such as Wild Ginger and Foamflower, you can enhance your garden’s beauty while supporting local ecosystems. Regular monitoring and maintenance will help ensure your garden remains a thriving, diverse habitat.
